Here is your 20GB of random data uploaded with my browser on a dockerized Jirafeau with default config:http://e-corporation.info:52140/f.php?h=0d9oPQOSbsum:1424b38c491e03249c1159bd9695ded3783ca61efa24528b69467509cba612fc3ba900ce156d8701d2e010b2797daf9ba98164e13ac28649eb038d9127fc6cbc

Also, I admit that the upload process is not very robust for sush large files. Problems are identified and will probably be fixed :)
